摘要：

In this paper, we consider non-orthogonal multiple access (NOMA) transmission with linear precoding techniques in downlink multiuser indoor multiple-input multiple-output (MIMO) visible light communication (VLC) systems. In particular, we propose a MIMO-NOMA transmission scheme in which the users having highly correlated channels are grouped into a single cluster and a common precoder is designed for all the users within this cluster. For the proposed scheme, we present an algorithm for grouping the users into clusters based on the correlation among their channel gains. Our performance results show that the proposed MIMO-NOMA transmission scheme achieves significantly higher spectral efficiency as compared to the conventional multiuser MIMO precoding schemes and can serve more number of users simultaneously.
